PS4 Pro Boost Mode Delivers Almost 40% More Performance For Certain Games


The PS4 Boost Mode is being marketed as one of the main selling points by Sony before the release of the upcoming 4.5 software update for PS4 Pro console. And latest test results are in, which confirm that the PS4 Pro Boost Mode is indeed capable of increasing performance by as much as 38% for certain game titles.

This Boost Mode, also dubbed as Beast Mode, is coming with the next major 4.5 Software update for the PS4 Pro. This new Boost/Beast Mode will allow some unpatched games to perform at an higher than usual level on PS4 Pro. Difference in the performance levels is palpable in the recent gameplay videos that have surfaced online.

This discernible improvement in gaming performance will surely be of great use, especially on titles that come unpatched or yet to receive a patch. Eurogamer’s Digital Foundry has tested the Boost Mode for Sony PS4 Pro console. And the results have shown that some unpatches games have performed 40% better than when run on a normal (non-Boost Mode). Check out the different for yourself in the video below:

Different in performance improvement varies from low to high across the spectrum. But, all in all, overall performance boost can be said to be of great use to the owners of the Sony PlayStation 4 Pro model running on Software 4.5.

Although, some titles, such as Killzone Shadow and Knack have seen only 14% jump in performance level, other titles like Assassin’s Creed Utility by Ubisoft and Battlefield 4 by EA performed way better than expected in the Boot Mode. However, most significant increase in performance level was seen in the F1 2016, Assetto Corsa, and Project Cars, with the last one performing up to 38% better in Boost Mode than on a normal game mode in PS4 Pro.

When the Boost Mode is enabled, CPU and GPU powers are ramped up to funnel in extra system resources for rendering games at higher level. Boost Mode also increases memory performance to make sure games keep running at an above average rate. According to Eurogamer, they asked Sony about ‘modest’ GPU boost (2.3x FLOPS), and below is the Sony’s reply:

“Boost Mode has been designed to provide better performance for those legacy titles that have not been patched to take advantage of the PS4 Pro’s faster CPU and its faster and double-sized GPU,” Sony says. “This can provide a noticeable frame-rate boost to some games with variable frame-rate, and can provide frame-rate stability for games that are programmed to run at 30Hz or 60Hz

“Depending on the game, the increased CPU speed may also result in shorter load times. Boost Mode is not guaranteed to work with all titles, however, turning the setting off will allow the game to be played in a mode that replicates the standard PS4. As an aside, the older unpatched titles that run in Boost Mode are unaware that they are running on a PS4 Pro and consequently don’t take full advantage of the PS4 Pro capabilities; power consumption for these games will therefore be a bit lower compared to playing a newer title.”

If these performance results of the Boost Mode are any indication, we may see significantly better performing games on PS4 Pro starting from the upcoming PS4 v4.5 software update.
